2 is a system block diagram electrically showing the configuration of a cash register having an accounting memory protection device of the present invention. As shown in this figure, the ECR of the present invention has a key input unit 10 for generating various key codes for mode designation and money registration, and a RAM 30 for storing various data generated during a program or a transaction set by a user. A printer for issuing a large amount of receipts and various processing results under the control of the central processing unit 20, a ROM 40 storing a system operation program and a program for implementing the method of protecting the accounting data of the present invention. 50), under the control of the central processing unit 20, the display unit 60 for displaying various information related to the transaction, the accounting memory 80 for storing sales data, the accounting for controlling the read / write operations of the accounting memory 80 The memory control unit 70, the opening detection unit 90 for detecting whether the case (not shown) covering the ECR main body on which the accounting memory 80 is mounted, the warning generation unit 95 for generating a warning sound, and the like; Key-scan the input unit 10 and specify the mode of the ECR according to the received key code, perform various functions in the designated mode, and based on the signal input from the opening detection unit 90, an accounting memory case (not shown) The central processing unit 20 that controls the warning generating unit 95 to generate a warning sound or the like when a non-appropriate person attempts to open an accounting memory case (not shown) by judging whether or not the unsealing party is justified in the case of opening). It is provided with.

In the opening detection unit 90, the variable resistor is coupled with a screw (not shown) for fastening the accounting memory case (not shown) to the cash register body when the accounting memory case (not shown) is fastened, and the screw from the outside (not shown). The resistance value rises to release the fastening of), which will be described in more detail with reference to FIG. 3. Therefore, when the resistance value is greater than or equal to the predetermined value, an H (High) signal is generated from the comparator. When this signal is input, the central processing unit 20 determines that the accounting memory case (not shown) is opened.

3 is an exemplary view briefly showing the mechanical configuration of the tear detection unit in FIG. As shown in this figure, the tear detection unit 90 of the present invention includes an accounting memory case 110 covering an ECR main body 130 on which an accounting memory 135 in which sales data is stored, and an accounting memory case. A screw 120 for fastening the 110 to the ECR body 130, and a rotation adjusting knob 105 positioned opposite to the screw 120 and engaged with the screw 120 when the accounting memory case 110 is fastened. It is made with a variable resistor (100).

When the accounting memory case 110 is fastened with the screw 120, the screw 120 is engaged with the rotation adjusting knob 105 of the variable resistor 100 positioned to face the screw 120. Here, when the screw 120 is completely fastened, the resistance value of the variable resistor 100 becomes lowest. As described above, with the screw 120 and the rotation adjusting knob 105 of the variable resistor 100 coupled, someone pulls out the screw 120 to unfasten the accounting memory case 110. When the screw 120 is rotated, the rotation adjustment knob 105 is also rotated to increase the resistance value. When the resistance value rises above a predetermined value, the H signal is output from the opening detection unit 90 to the central processing unit 20 so that the central processing unit 20 may know that the accounting memory case 110 is being opened.

4 is a flowchart for explaining a method of protecting an accounting memory of the cash register of the present invention. As shown in this figure, in step S10, the signal coming from the tear detection unit 90 is checked, and the flow proceeds to step S12, and the signal coming from the tear detection unit 90 is an H signal, that is, the accounting memory case. It is determined whether 110 is opened. When the accounting memory case 110 is opened as a result of the determination in step S12, the process proceeds to step S14 and a password for determining whether the person who wants to open the accounting memory case 110 is legitimate is to be input. In this case, for example, the display unit 60 outputs a message of 'Please enter a password number', and proceeds to step S16 and the password received from the user according to the message output in step S14 is set in advance. Determine if the password matches. Here, the password is to be handled by a service engineer or a specific person authorized in the country. If the password received as a result of the determination in step S16 does not match the preset password, an unjust person wants to open the accounting memory case 110. In this case, the process proceeds to step S18 and the accounting memory case 110. ), An error message or a warning sound is generated to prevent the person from being able to handle the accounting memory 80 so that the accounting memory 80 cannot be handled. In addition, if there is an ECR or the like connected to the corresponding ECR, a message may be displayed to warn that the accounting data may be damaged by an unfair person by communication.

On the other hand, if it is determined in step S16 that the input password matches the preset password, the process proceeds to step S20 to determine whether the reason code for opening the accounting memory case 110 is input. If the reason code is entered as a result of the determination in step S20, the process proceeds to step S22 and the accounting memory case 110 stores the input reason code, the person in charge, the time of occurrence, and the like in the accounting memory 80. When and for what reason was it opened by whom?
